The big problem with "free market schools," BTW, is that the state is the educator of last resort. There's a real adverse selection problem if education suppliers can take $X to educate the most desirable students, leaving $X per student for the most difficult to educate students. A huge proportion of public educational expense is special education. If you don't want to give up on special education, this is difficult to do. I favor policies like vouchers for ~33% of public educational cost to be used at private institutions. This is enough to make private education more affordable to many more families (especially with institution financial aid), but could possibly increase resources-per-student for the remaining students in public schools.
